Appl. No.:

11/037792

Inventors:

Ashvin Lad - Indianapolis IN, US
Michael DeBruyne - Bloomington IN, US
Thomas Osborne - Bloomington IN, US

International Classification:

A61F002/06

US Classification:

623001130, 623001150

Abstract:

An endoluminal prosthetic device for placement in a body lumen is formed by stitching stents to a graft. A first or anchoring stent is used for securing a graft made of biocompatible material that forms at least one lumen. There is also a second stent. The first and second stents each include a plurality of struts and apices between the struts. At least two of the apices in each of the first and second stents are secured to the graft by stitches. A running suture links at least one stitch of the first stent and one stitch of the second stent. The running suture linking the first stent and the second stent adds strength to the stitches and better secures the first stent to the device. The endoluminal prosthetic device may be used in an aortic vessel to treat stenoses or aneurysms.

Abstract:

An endoluminal prosthetic device is formed by attaching a stent to a graft. The stent is a plurality of struts and joints or apices between the struts. At least one apex of the stent may be attached to the graft with at least two stitches sharing a penetration in the graft. This more firmly anchors the stent to the graft, preventing separation of the stent from the graft. By using at least one opening or penetration in the graft for more than one stitch, the number of penetrations or openings in the graft is minimized. This has the advantage of maintaining as much as possible the integrity of the graft while minimizing leakage and complications.
